Al Hosn, also known as the White Fort, is the oldest existing structure in Abu Dhabi. Although regarded as a fort, Al Hosn is actually a palace. Built in 1793, Al Hosn was the seat of government in the 18th Century and also served as the residence of the first family of the government. Today, Al Hosn serves as a cultural centre and houses the Centre for Documentation and Research of Abu Dhabi's Cultural Foundation. One of the major highlights of Al Hosn is its architecture. The palace has undergone many modern renovations and the complementarities of the modern designs with the old architecture gives the structure a unique beauty. The remarkable courtyard, stunning white-washed ramparts and the cultural displays at Al Hosn are also some of the major highlights.
